How to size sandals correctly
Measure first, label second
Pick a tape measurement and match it to the chart. Labels (S/M/L, US/UK/EU numbers) drift between brands; the underlying body measurement does not. Foot length in cm or inches is the only measurement that travels across all systems — US/UK/EU labels are unreliable across brands.
Picking between two sizes
For sandals, half a size up is almost always right — foot expansion in heat is real, and an over-tight strap leaves marks. Adjustable strap sandals (Velcro, buckle) absorb half a size of difference; slide sandals do not.
Brand and regional variation
The same labeled size can differ by a full size between brands and regions. Asian brands generally run a half size smaller than US brands; European brands fall in between. When in doubt, use the centimetre or inch measurement on the size chart, never the letter.
Common mistakes
- Sizing by your old favourite without checking the new brand's chart.
- Skipping the measurement step. Body shape changes; old numbers go stale.
- Picking too tight in non-stretch fabrics — they don't break in the way leather does.
- Trusting a single review's "runs small / runs large" without looking at the reviewer's measurements.
